"Dear Domino's Pizza guy, Thank you for acting kool and making casual conversation, even though we both knew you knew I was high," reads one comment on the "Confessions" page for the University of Houston.

UH's student-run site is nearing 14,000 "likes" since launching in late January, and college administrators are warning students that the posts are public and potentially permanent and hurtful.

Similar sites have sprung up for Rice University, the University of Texas and local high schools, including Lamar, DeBakey and Carnegie Vanguard, a Houston campus for gifted students. The trend has spread as far as Singapore and New Zealand.

"It's like a big thing on campus," said Betty, a UH junior from Dallas who declined to give her last name. "If anything, I'd say it's bringing the school together. It's like something everyone can relate to. One of my friends said a professor told students to peel their eyes off 'UH Confessions' to look at the PowerPoint (in class)."

Could be consequences

The confession comments appear anonymously on Facebook, getting around the site's policy requiring users to provide their real names by linking users to an outside website such as SurveyMonkey. Site moderators then approve the "confessions" to appear on Facebook. It's possible the comments aren't even coming from students. However, people respond to the posts with their real names and profile photos showing.

"We urge students to consider the consequences a posting could have for them and others in the future," UH spokesman Richard Bonnin said in a statement.

The "UH Confessions" site opens with this prompt: "Go to this page and type any confessions you've been dying to get off your chest! It's 100% anonymous, not even the mods can see."

Recent posts include:

"I conceal carry on campus. Screw getting robbed."

"My roommate used to write people's papers for them and get paid. One day a guy came into our room all pissed off because he got a D on the paper she had written for him and he demanded his money back. She refused but she didn't get much business after that."

"i recently just got broken up with and it sucked... i have been putting up a front that im good and that im fine but im not. i just miss her and everything about her."

Cyberbullying warning

The administrators of the UH site declined to reveal their names but responded to questions via email. They said two students started the page, and they get 500 to 600 confessions daily, though not all are posted.

"One of the initial goals or aims in starting the page was to attempt to create a closer-knit campus by allowing the students to share stories that others could relate to," the "UH Confessions Team" said. "We wanted to promote the Cougar spirit. Post(s) that are openly hateful or derogatory towards a certain group will generally not be posted."

One recent post mentions seeing an unidentified girl's breasts in the locker room. Another says, "Crushing on underclassmen, does that make me a pedophile? If so, i blame the upperclassmen guys for not being sexy enough. Or then again I might just be a cougar."

Gay, who has a son at Carnegie, said she urges students to play nice.

"Cyberbullying or just cyber untruths can ruin people's lives," she said.

Houston school district spokesman Jason Spencer said principals do not actively monitor students' personal use of social media but can act if they find questionable comments.

For example, Spencer said, the DeBakey High principal has "reminded students that they can be held accountable for statements that might be interpreted as bullying."
